Well, there are a lot of complexities, but the gist is the same. It is between the remote console and the terminal you are interfacing with. ipmitool or similar is just a bridge between the two.
FWIW, confluent (https://www.youtube.com/watch?v=G_lDaktYnsQ) is endeavoring to track some of the interesting states that might have happened behind the terminal's back (e.g. shift in character set, cursor application mode) and replay the appropriate requests to a client that connects. Even then, however, it's still up to the terminal implementation to honor those sequences, confluent is just trying to help in the cases today when a terminal is likely to miss them. One thing fixed by this is ESXi serial console looking terrible and not having working arrow keys when you connect, for example. The IPMI standard also includes a way for a client to request boot to setup. I know it works on current IBM systems. 'rsetboot <nodes> setup' is the xCAT command. I'm guessing that ipmitool chassis bootparam set bootflag force_bios is the equivalent. Even as I have no problems hitting F1, I generally prefer to that so I don't even have to watch the screen at the time.

For example, Dell 610 has a BIOS option to display it's own BIOS set up screen using vt100 or ANSI BUT in either mode it only accepts F2(ANSI) which is resed and and can't be used by vt100. The net result is you can change the protocol used to display the characters but the keyboard input is only ANSI. And there there other vendors, SuperMicro, that do totally withered and odd things.

The vt100 facet of it is whatever terminal ipmitool is executed in (e.g. ipmitool inside gnome terminal, xterm, konsole, whatever has no issues with function keys and other VT100 behaviors). If ipmitool does not work under your terminal type, it would be the terminal ipmitool is being run in that is limited rather than ipmitool.

What would it take to get vt100 support in ? For instance, when the system on the other end of the sol session is rebooting, you are supposed to type <F2> to get into the BIOS Setup screens. But since sol does not support <F2> (a vt100 key), the user must know to type <Esc> 2 . If sol had a vt100 support option, then they would be able to use the <Fn> keys directly. -- Ross Amans Systems Engineer Newisys div of Sanmina 5385 Mark Dabling blvd Colorado Springs, CO 80918 719-884-8714 (work) 719-287-4446 (cell) CONFIDENTIALITY This e-mail message and any attachments thereto, is intended only for use by the addressee(s) named herein and may contain legally privileged and/or confidential information.
